Linear supplies have the least power ripple, but generate a lot of heat and weight inside your case. There aren’t a lot of high power linear options though so you will need more than one supply for your power requirements I suspect. L-1 look like they have a great linear supply. Hinton is “the best” according to himself. I looked at it but the weight and size of the units put me off (not to mention the cost).
Also with linear supplies you have to be aware that mains power will be inside your case, so you need to make sure you don’t electrocute yourself!
Supposedly they are ‘the best’ option but I’ve not had issues with switched supplies.
Having a good distribution board helps I suspect. I know some people have had issues with flying bus cables but I’ve never used them. Some distro boards are passive and others offer linear regulation for the headers. Lots of options.
Right now my two systems are running:
- Eskatonic distro boards and meanwell bricks
- Amalgamod distro boards and meanwell bricks
Both supply ample power for my needs and the Eskatonic system is quite scalable (I think Perfect Circuit stocks them).
Have also heard very good reviews about Trogotronic power systems. I was going to go that way for my big case but the builder used Eskatonic and it has been just great.
The only reason I’d switch to linear is if I were having issues with switched- but I’m not so switched is A Ok!!
One thing I consistently see / hear on the forums is that you need to allow some headroom for your draw, and not run your system more than 80% of so of it’s rated capacity. If you are close to it then you may have heat / power on problems. I did find heat issues with my Amalgamod when I pushed it to its limits, but balancing the loads per zone helped tremendously.
So buy more power than you need would be my advice.
